Proteomics is a large-scale comprehensive study of a specific proteome, including information on protein abundances, the variations and modifications, as well as their interacting partners and networks. In discovery proteomics, proteome analysis can be performed in two different strategies, bottom-up and top-down approaches, respectively. In the bottom-up approach, a crude protein mixture undergoes protease digestion first, and then separation by liquid chromatography, followed by MS analysis. In the top-down method, proteins are characterized by MS without prior proteolysis. This type of approach has the advantage of providing greater sequence coverage, resolution of sequence ambiguities and preservation of PTMs. https://www.creative-proteomics.com/services/proteomics-service.htm

Peptide Mass Fingerprinting (PMF), also known as mass fingerprinting, was developed in 1993. It is a high throughput protein identification technique in which the mass of an unknown protein can be determined. PMF is always performed with Matrix-assisted laser/desorption ionization time of flight (MALDI-TOF) mass spectrometry.

MS is widely used in free oligosaccharides, glycosaminoglycans as well as the glycan portions of glycoproteins, proteoglycans, and glycolipids. And there is a wide range of MS techniques are available for glycomics analysis. As research continues on MS-based glycomics analysis, we believe that clear understanding the mechanisms of important biological processes will be achieved in the near future. https://www.creative-proteomics.com/

Creative Proteomics: Glycomics Analysis by Mass Spectrometry

Glycan microarray has become a sensitive and versatile approach for the analysis of glycosylation changes in complex biological samples. It can not only investigate glycan-GBPs binding but also provide kinetic analysis of glycan–protein interactions. Nowadays, this application has rapidly expanded and now achieves successful discrimination of selective interactions between glycans and, not only proteins, but also viruses, bacteria and eukaryotic cells, and most recently even live cell responses to immobilized glycans. Glycan microarray can be used to discover functional glycans, characterize glycan-processing enzymes, and detect pathogens for diagnosis. It is also suitable for monitoring multiple molecular interactions with biomolecules where glycans are involved, offering a large variety of bioassay options.

Glycan Microarray Assay — Creative Proteomics

Proteins are the critical players in molecular recognition at the core of all biological processes. They can interact with the other components of cells, such as small-molecule metabolites, nucleic acids, membranes, and other proteins to build supramolecular assemblies and elaborate molecular machines that perform all sorts of functions, from chemical catalysis and mechanical work to signaling and regulation. As one of the most important interactions, Protein-Protein Interactions have been studied widely. So far large scale protein-protein interactions have been identified, and all the generated data collected together in specialized databases, enables the creation of large protein interaction networks. https://www.creative-proteomics.com/services/protein-protein-interactions-analysis-service.htm

Techniques for Protein-Protein Interaction— Creative Proteomics

Label-free protein quantification is a mass spectrometry-based method for identifying and quantifying relative changes in two or more biological samples instead of using a stable isotope-containing compound to label proteins. There is no limit on the number of samples in label-free protein quantification and it’s in principle applicable to any kind of sample, including materials that cannot be directly metabolically. It is ideal for large-sample analyses in clinical screening or biomarker discovery experiments.   https://www.creative-proteomics.com/
